Danny Velez has for more than 25 years been one of the driving forces positioning the company as a leading provider of high-performance diets and best-in-class technical services and training. Up to now Danny Velez has been heading the daily operations being in close contact with customers as well as suppliers.

“I fully respect the decision taken by Roberto Boloña and we highly appreciate his valuable contribution to Alimentsa during the past years. I am very satisfied that Danny Velez has accepted the new challenge securing continuity and taking lead in integrating Alimentsa into BioMar Group. We right now are focused on positioning Alimentsa even stronger in Latin America and we expect to be able to present very tangible actions within a short timeframe. I believe that we can together create synergies in regards to the development and delivery of high-end products and services to the Ecuadorian shrimp farmers”, explains Henrik Aarestrup, VP Emerging Markets, BioMar Group.

Roberto Boloña hands over a strong company having supported a smooth acquisition process, now positioning BioMar Group among the leading shrimp feed producers in Latin America.

“Personally, I am very honoured to be chosen to lead this important step forward for Alimentsa. I see a huge opportunity developing Alimentsa with support from the global innovation teams in BioMar. At the AquaExpo in Guayaquil our customers were truly excited about the new opportunities ahead and I am sure that together we will make leaps and bounds towards contributing to the innovation of the aquaculture industry in Ecuador”, states Danny Velez, General Manager in Alimentsa.

21/11/2017: Giant freshwater prawn

by Wee Wen Chen, Master of Science (Aquaculture and Marine Biotechnology)

“Effects of dietary prebiotic fructooligosaccharide supplementation on growth performance, hepatopancreas histology and intestinal short-chain fatty acids in giant freshwater prawn Macrobrachium rosenbergii”

Aquaculture is one of fastest food producing sector in the world. A persistence goal in various type of aquaculture is to maximise the efficiency of production to optimise profitability.
 

The giant freshwater prawn, Macrobrachium rosenbergii is a valuable aquaculture species in many countries due to its commercial value and their aquaculture production has only moderately risen from 196,848 to 213,958 tonnes between 2004 and 2015 (FAO, 2017).

Some of the constraints in the expansion of this cultured organism include high feed costs, slow growth rates, poor seeds quality and diseases. Sustainable M. rosenbergii farm production could be achieved when good seedling quality, improved broodstock strain and optimised formulated feed are available to the local prawn hatcheries.

Hence, there are few important areas that requires further research. Besides aquaculture system development, genetic and breeding improvement, health and environmental management, evaluation on feed supplementation is necessary for sustainable prawn farming.

In addition, the rise in feed ingredient prices also have an impact to the aquaculture production cost. It is possible to reduce the cost of production if the prepared diets not only provide essential nutrients but also increase growth and health development of the aquatic animals in commercial aquaculture. These problems may potentially be mitigated by dietary prebiotics.

Dietary supplements of sustainable feed additives such as prebiotics can impart beneficial effects on fish or crustacean growth and that turn direct into financial benefits by decreasing feed cost per unit growth of aquatic animals. The use of prebiotic appears more practical to stimulate favourable condition for beneficial bacterial in the gastrointestinal (GI) tract of aquatic animal.

Also, if the survival, growth performance and feed efficiency of aquatic farming animals are increased, the cost of production is likely to be reduced. Then, feed additives have a great potential to increase sustainability of aquaculture production. Good formulated feeds supplementation could yield healthy and better growth seedling, resulting in good quality prawns.

Prebiotics
Prebiotics are often confused with probiotics. Prebiotics are indigestible food ingredients that may improve the growth and health of the host by promoting the growth of beneficial bacteria in the GI tract (Ringo et al., 2010).

When improving the symbiosis between host and beneficial microbiota, this can indirectly improve nutrient utilisation, metabolism, disease resistance, immunity and survivability of the host (Gatlin III & Peredo, 2012). Prebiotics potentially represent eco-friendly additives since these are natural feed ingredients that include alginate, inulin and various oligosaccharides. Although prebiotics are carbohydrates, not all indigestible carbohydrates are prebiotics (for review, see Ringø et al., 2010).
